STAPLING- MACHINE.

SPECIFICATION forming part of Lei-.ters Patent No. 621,748, dated March21, 1899. Appiaaaon mea December 7,1898. serianaeatl. (roman.)

To a/ZZ whom it may concern,.-

Be it known that I, AUGUST H. BUcHIIoLZ, a citizen of the United Statesof America, residing at Washington, in the county of Franklin and Stateof Missouri, haveinvented a new and useful Stapling-Machine, of whichthe following is a specification. Y

The object of this invention is to provide a stapling-machine forreadily and conveniently connecting together two or more pieces ofleather in manufacturing boots and shoes or repairing them, theparticular 'construction and disposition of the parts producing amachine of this character which shall be simple and cheap and bythe useof which the operation of applying the staples to the leather andclenching them thereon can be accomplished quickly and in av thoroughmanner.

The invention contemplates the employment in the machine of automaticfeeding mechanism for the staples, a plunger or stopblock for firmlyholding the work in place upon the anvil of the supporting-arm, areciprocating staple-driver operating through the plunger or stop-blockinto which the staples are fed one at a time, .a rod extending upwardfrom the stop-block and having an inwardly-projecting arm through whichtheupper part of the stapledriver passes, and springs located above andbelow said arm and bearing against the opposite sides thereof by whichthe plunger or stop-block is automatically operated'through theintervention of the staple-driver, while the latter is reciprocated bymeans of a lever connectedto a footlever.

The following specification enters into a detail description of mymachine for driving and clenching staples, reference being had to theaccompanying drawings and to letters thereon which designate thedifferent parts, and what I claim in the peculiar construction andarrangement of parts and desire to protect by Letters Patent is morespecitically stated in the appended claims.

In the accompanying drawings, forming part hereof, Figure l is a sideelevation of a stapling-machine constructed in accordance withmyinvention. Fig. 2 is al front elevation of the machine. Fig. 3 is aside elevation, the

to be attached to a work-bench, table, or other suitable support, and tothis end the frame or body of the machine is provided with arearwardly-projecting horizontal flange a, which bears flat upon thework-bench or table and through which the securing bolts or screws arepassed, so that the frame or body will project in front of thework-bench. The body or frame of the machine presentsv practically ahorizontal yoke, from the contiguous ends of the arms of which theattaching-Hang@ a projects rearwardly, as shown, the lower arm B formingthe support or anvil upon which the work is placed, while the upper armC carries the staple feeding and driving mechanism, which I shall nowproceed to particularly describe.

The forward end of the upper arm C is enlarged or extended upwardly toform a head D, and in one side of this head is a vertical groove orrecess d, extending the full length of the saine. In the lower part ofthis groove or recess plays a plunger or stop-block E, to which issecured an operating-rod e, extending upward at one side of the grooveor recess and provided at its end which is beyond the head with an arme', while in the upper part of said groove or recess plays the stem f ofthe staple-driver F. From the rear wall of the groove or recess dprojects a guidefiange d, which enters corresponding grooves in the rearside of both the stem f and stopblock E, the said guide-flangeterminating a slight distance above the lower end of the rear.

wall, for the purpose hereinafter mentioned.

The staple-driver F projects from the center of its stem and ispractically T shape in crosssection, the said staple-driver having amovement in a corresponding recess f', extending vertically through theplunger or stop-block E, this vertical recess in the plunger or stop,block being practically a continuation of the Ioo I groove that receivesthe guide-flange d. The lower end of the plunger or stop-block is cutaway, as shown, exposing the recess through which the staple andstaple-driver pass, so that the operation can be watched by theoperator, and at the rear side of this lower end is secured across-piece g, forming a guide for the staple.

The staple-driver is reciprocated by means of a yoke-lever H, which ispivoted at its forward end to a link I, pivotally supported by a pin z',passed through ears projecting from the upper part of the head D, thesaid lever being connected to the stem of the stapledriver byv a pin h,which extends through slots in the side pieces of the head and throughan opening in the stem. posed between the lever and main frame toautomatically move the lever, so that in the normal position of theparts thestaple-driver will be elevated. The yoke-lever is operated froma treadle or foot-lever (not shown) by way of the connecting-rod h2.

Movement is imparted to the stop-block or presser-bar E through theintervention of the staple-driver, and to this end a bolt K is passedthrough an aperture in the arm e of the operating-rod c and screwed intothe upper end of the shank f of the staple-driver, helical springs k 7.5encircling the bolt to bear upon opposite sides of the arm. rlhe upperspring la contacts with the head of the bolt, while the lower spring 7a'contacts with the upper end of the stem f.

The lower arm B of the main frame presen ts a. support for the work, theouter end forming an anvil which acts in conjunction with thestaple-driver to clench the ends of the staples upon the under side ofthe lea-ther, and for this purpose the arm is provided with a threadedaperture receiving a screw L, the upper end of which is flush with theanvil and has formed therein curved recesses l Z, which serve to turnvthe ends of the staples inward. The arm B dips downward from the anvil,and the shape of the frame leaves an open yoke which permits the work orshoeupper to be turned in applying staples along the seams to reinforcethem.

To provide for automatically feeding the staples into the stop-block orpresser-bar below the staple-driver, the arm C of the frame is providedon one side with a horizontal recess c, which communicates with thevertical recess d in the head at the lower end of the guide-fiange d. Inthis horizontal recess is secured a staple-carrying bar M, upon theupper edge of which the staples are strung, as

shown, the staples being forced into the stopblock or presser-bar bymeans of a follower N, connected to a rubber band n, which maintains apressure of the follower against the line of staples. The follower isprovided with three or more projections n, so that the connection of therubber band thereto can be changed to insure a full movement of saidAspring 7L' is inter-- follower. Though I have shown and described arubber band for moving the follower to cause a proper feed of thestaples, a spring-weight andy cord'or other equivalent device could beused, and it will be noted that the staple-carrying bar can be readilyremoved to string a supply of staples thereon. The lower part of theforward end of the staple-carrying bar is cut away to receive thecross-piece g at the lower end of the stop-block or presser-bar.

In the normal position of the parts of the machine a staple is fed intothe recess of the stop-block or presser-bar below the stapledriver oropposite flanges thereof, and upon a downward movement of theoperating-lever the staple-driver is rst moved a short distance to bringthe staple to the lower end of the presser-bar. The head of the boltcarried by the staple-driver then compresses the spring 7a upon theoperati n g-rod lof the presserbar, forcing the latter down upon thework, and a further movement of the lever causes the staple-driver toforce the staple through the work and the ends are clenched on the underside by means of the anvil. Vhen thc operating-lever is released, theparts automatically resume their normal position, and the staple-driver,moving to a position a slight distance above the inner end of thestaplecarrying bar, permits of a staple being fed into the presser-bar.The lower end of the guide-flange d', being a slight distance abovethein ner end of the staple-carrying bar, forms a guide for the staplesand prevents them moving upward when the presser-bar is reciprocated.The presser-bar bears upon the work by pressure of the spring lt, andthe length of the staple-driver proper is such with respect tothepresser-bar that the stem j' will contact with said presser-bar when thelower end of the staple-driver is at the lower end of the presser-bar,thereby forming a stopv to limit the movement of the staple-driver andprevent it from being forced too far into the work.

A plate O covers the working parts in the head of the stapling-machine,and by the particular construction and arrangement of said parts asimple, compact, and durable machine is provided. upon each movement ofthe operating-lever the presser-bar is brought down upon the work tohold it in place, and then the staple-driver acts to force a staplethrough the work and clench it thereon, said presser-bar also limitingthe movement of the staple-driver.

The machine is particularly adapted for reinforcing the seams of bootsand shoes, and the particular construction of the frame permits the shoeto be readily manipulated. The

machine may also be used for connecting pieces of leather together forvarious purposes and being comparatively small can be attached to awork-bench or table without occupying very much room.
